T all whom t mag/concern:

Be it known that I, JOSEPH ELI BERTRAND,

of Boston, in the county of Suffolk and State of Massachusetts, haveinvented certain new and useful Improvements in `Sole Rough-L Roundingand Channeling Machines, of which the following, taken in connectionwith theac'companying drawings, is a specification.

My invention relates to sole rough-round-- io ing and channelingmachines; and it consists in certain novel features of construction,arrangement, and combination of parts, which will be readily understoodby-reference to the description of the accompanying drawings and to theclaims hereto appended and in which my invention is clearly pointed out.

Figure 1 of the drawings is a plan of a ma-` Fig.`2 is a; side elevationlooking toward the lower side` Fig. 3 is an elevation of the oppo` Fig.5`

machine with the channel-cutters and the gage. Fig. 8 is a frontelevation of the same parts and the trimming or rough-rounding cutter.Fig. 9 is a vertical section on line .e 5

Fig. 10 is an elevation of the inting plater or anvil against which thetrimming-cutter acts. Figs. 7, S, 9, and 10 are drawn to an enlargedscale. Figs. 11 and 12 3 5 are respectively a side elevation and atransverse section 'of the oscillating channel-cut-v ter drawn to astill larger scale; and Figs. 13 and 14 are respectively an elevationand an end view of a portion of a sole, illustrating the 4o trimming andchannel cuts.

In the drawings, A is the frame of the head of the machine, constructedand arranged to be mounted upon a column or bench. (Not shown.) Theframe A has mounted in suit# able bearings formed therein the shaft 1,upon which are mounted the cani-disk 2 andthe cylinder-cams 3 and`4between said bearings and thedriving-wheel 5 on the projecting endthereof,A as shown. I

Fig. 7 is a z5 plan of the front portion of the nose of the The frontend of the upwardly-projecting 5o plate-like portion of the frameA hassecured thereto the stationary pendent guide-arm 6, and also has pivotedthereto the crescent- `shaped lever 7, to the front end of which issecured the feed-plate 8, the inner face of which has set therein theplate 9, of soft metal, and the lower portion of which is serrated orroughened to insurea good hold upon the surface of the rand or sole tofeed the work, as shownin Fig. 10. The rear end of the lever 6o 7 hasset therein the stud 10, upon which is mounted the truck 11, upon whichthe facecam formed upon the periphery of the camdisk 2 acts to vibratesaid lever 7, said truck being keptin contact with said cam by thetension of the spring L. The lever 7 is mount- 'ed upon the pivot-pin12, so as to be movable laterally or lengthwise of said pin to assist infeeding the Work.

A three-armed lever 13 is mounted upon a 7o vertical pivot-pin 14,secured in a fixed position in the ears or bosses 15` and 16, formed onthe frame A, as shown in Fig. 3. The rearwardly-projecting arm of thelever 13 carries at its rear end a cam-truck which is 75 acted upon bythe path of the cylinder-cam 3 to vibrate said lever `13, and the upperforwardly-projecting arm of said lever is connected at its front endwith the lever 71by a swiveling block 17 to impart the necessary 8olateral movement to said lever 7 for feeding the work.

An arm 18 is pivoted to the frame A bythe verticalpin 19 and is providedin itsupper side with a longitudinal groove, in which is mounted, soas-to bemovable endwise therein, the bar 20,which is held in place insaid groove by the caps 21 and has secured to its frontend thetrimming-cutter 22, and to the upper side of its rear end the swivelingblock 23, which 9o is engaged by the forked arm of the elbow lever 24,the other arm of which carries a camtruck 25, which is acted upon by thepath of the cylinder-cam 4 to vibrate said lever and impart to said bar20 an intermittent recip- 95 rocation, as shown in Figs. 4 and 5. Thearm 18 is provided with the laterally-projecting ear 26, to which ispivoted one end of the link 27,` the other end of which is pivoted tothe front end of the lower forwardly-projecting arm of the lever 13, bythe vibration of which the arm 13 and `cutter-bar 2O have impartedthereto a lateral vibratory motion in unison with the lateral motion ofthe .lever 7 and feed-plate 8 for the purpose of feeding the work.

The base-plate of the frame A has formed upon its under side twodownwardly-projecting ears 2S, between which said plate has cut throughit a rectangular opening, in which is mounted, so as to be verticallymovable therein, the block 29, having an inverted-T-shaped groove formedin its upper side, in which is fitted, so as to be movable endwisetherein, the nose-piece 30, upon which are ad justably secured in fixedpositions the gage-plate 31 and the cutter 32, and also has mounted in asuitable bearing therein the short shaft 33, the axis of which is atright angles to theline of feed of the work and has formed upon itsfront end the circular cutter 34, concentric with said shaft, butconnected thereto by the eccentric neck 35, as shown in Figs. l1 and 12,said cutter having a knife-edge extending from one side of the neck 35around to the opposite side thereof. The shaft 33 has firmly securedthereon the toothed segment 36, with which the teeth of the rack 37engage, as shown in Fig. 9. The rack 37 has set in its endthelaterally-projectingpin 38, with which the forked end of the lever3S, secured lupon `the front end of the shaft 39 engages, to im part tosaid rack a reciprocating movement, and thereby cause an oscillatingmovement to be imparted to said cutter 34 to cut the channel. The shaft39 is mounted in bearings in the ears 40 and 41, formed upon the frameA, in such a manner that it is free to be moved endwise and oscillatedaboutits axis therein and has fitted upon its rearend the arm 42, thehub of which yis divided and embraces the ear41 to prevent forward andrearward movement of said arm when the shaft 39 is moved endwise inunison with the movements of the nose-piece 30, said arm, however, beingconnected to said shaft by a spline and groove, so that said shaft iscompelled to move about its axis in unison with said arm, to which aseries of vibrations is imparted during about one-third of eachrevolution of the shaft 1 by the facecam '43, formed upon the side ofthe cam-disk 2, acting upon the truck 44, carried by said arm 42, asshown in Figs. 1 and 3, said truck 44 being held in contact with saidcam 43 by the spring 45.

A block or stand 46 is secured to the frame A above the forwardcap-plate 21 to prevent any possibility of `the front ends of the arm 1Sand bar 2O being forced upward during the cutting or feeding of thematerial.

The nose-piece 30 is limited in its forward movement by the adjustablestop-screw 47, toward which it is pressed by the spring 48, inclosed ina chamber in said nose-piece and acting against a shoulder on thefollower 49,

the rear end of which ahuts against the pin 50, as shown in Fig. 6. Thenose-piece 30 is moved to the rear for the purpose of placing the workin position by means of the cord or chain 51, secured to the screw-stud52,and after passing over the-pulley 53 is connected to a treadle nearthe floor, but not shown. The block 29 rests upon two eccentrics 54,which have bearings in the ears 2S and have secured thereon theradius-arms 55, the movable ends of which are connected by the link 56,to one end of which is pivoted one` end of the rod 57, the other end ofwhich extends through a bearing in the stand 53, between which and ashoulder on said rod is the spring 59, the tension of which moves thelower ends of said arms 55 toward the front of the ma chine.

A lever is pivoted to the frame A, is pro vided with a slot 6l toreceive the pin 62, and has connected to its lower end one end of thecord or chain G3, which passes to the rear over the pulley G4 and isconnected at its other end to a treadle near the iioor, but not shown,by means of which the link 56 and the lower ends of the arms v55 may bemoved to the rear against the tension of the spring 59, and thus turnsaid eceentrics, yso as to raise the block 29 and nose-piece 30 toreduce the distance of the channel from the rough rounded edge of thesole. The cutter 22 has a concavo-convex cutting edge, with its convexside downward, as shown in Fig. 8.

The guide-arm G enters the angular space between the rand and, upper ofthe boot or shoe and serves to guide the same as it is fed through themachine.

The operation of my invention is as follows: The several parts of themachine being in the positions shown in Figs. 1, 2, 3, and 4, theoperator retracts the nose-piece 30 by placing his foot upon the treadleconnected thereto by the cord or chain 51, then places the treadsurfaceof the sole against the gage-plate 31, with the lower ends of theguide-arms G and lOO IIO

feed-plate 3 bearing against the upper in proximity to the rand, andthen releases said treadle, when the reaction of the spring 43causesaforward movement of said nose-piece and a clamping of the soleedge between the guide-arm (i and said nose-piece. lf power be appliedto the wheel 5 to revolve itinl the direction indicated by the arro'w onFig. 2, the first effect produced is a forward movement of the bar 2Oand cutter 22 until its cutting edge has passed through the sole andcome in contact with the plate 9, caused by the action of the cam 4 uponthe lever 24. When the forward movement of the cutter is completed andwhile ysaid cutter remains in contact with said plate 9, the forwardends of the arm 18, the bar 20, cutter 22, and the lever 7, with thefeed-plate 8, are movedrtoward the left by the action of the cam 3 uponthe lever 13 to feed the work,which being pressed against the cuttingedge of the stationary cutter 32 as it is fed forward, a section of asha1? low incision G5 at right angles to the treadsurface of the sole isformed therein, as shown in Figs. 13 and 14. During the same time thatthe work is being fed the cam 43 is acting upon the truck 44 tooscillate the shaft 39 and cause a series of rapid reciproeations of therack 37 and a corresponding series of oscillations of the cutter 34,which cuts an incision 66 parallel, or nearly so, to the treadsurface ofthe sole arid extending from the incision toward the center of the sole,'a distance nearly equal to the diameter of said cutter 34, as shown inFigs. 13 and 14. The continuation of the revolution of the camshaft 1causes Vthe cutter 22 to recede to its rearmost position, while theplate 8 moves toward the front, and then the said cutter and feed-plateare moved toward the right to the positions occupied at the start, thework being prevented from being movedbackward by being clamped betweenthe guide-arm 6 and the nose-piece 30, these operations being repeatedat each revolution of the cam-shaft 1.

The distance of the channel from the rough rounded edge of the sole maybe varied by a` partial rotation of the eccentrics through the medium ofthe cord 63, the lever 60, the'link 5G, the levers 55, and the spring59.

I claim- 1. ln a roughrounding machine the combination of a yieldingnose-piece; a stationary guide-arm coperating with said nose-piece toclamp the solo edge; a reciprocating and laterallymovabletrimming-cutter; and a feed-plate constructed and arranged to movetoward and from said cutter and laterally in unison therewith.

3. The combination of the pivoted arm 18; v

the bar 20; cutter 22; elbow-lever 24; cam 4; the lever 13 connected tosaid arm 18; the cam 3; the lever 7; the feed-plate S; the cam 2 forvibrating said lever and the swiveling block -17 connecting said lever 7to an arm of the lever 13 all constructed arranged and operatingsubstantially as described.

4. In a channel-cutting machine the combi= nation of a work-feedingmechanism; a stationary critter arranged to cut a shallow slit at rightangles to the tread-surface of the sole as the work is fed past it; anda circular disk-likev cutter constructed and arranged to oscillate aboutits axis in a plane parallel or nearly so to the tread-surface of thesole and cut an incision from said shallow slit toward the center of thesole as it is fed toward said cutter.

5. In a sole rough-rounding and channeling machine the combination ofthe eccentrics 54,

54 mounted in bearings in the ears 28, 28; the block 29 supported uponsaid eceentrics and having an inverted-T-shaped groove formed in itsupper side; the nose-piece 30 fitted to and movable-endwise in saidgroove; the spring 48 for pressing said nose-piece toward the front; thefixed combined guide-arm and Work-clamping member,coperating with themovable nose-piece to hold the work; means for partially rotating saideccentrics to raise and lower said nose-piece and means for retractingsaid nose-piece away from the iiXed work-clamping member '6 against thevtension of said spring 48 to enable the work to be placed in position.

6. In a sole-channeling machine the combination of the yieldingnoselpiece 30; the gage- .plate 31, the stationary cutter 32 and theoscillating cutter 34 carried by said nose-piece; the toothed segment 36fast on the shank of said cutter 34; the rack 37 engaging said segment;the endwise-movable oscillating shaft 39; the lever 38 mounted on saidshaft and engaging said rack; the arm 42 connected to said shaft so asto oscillate therewith while said shaft is freely movable endwisetherein; the truck 44 carried by said arm 42; and the cam 43, allarranged to operate as set forth.
